Theory of Operation
This section provides a general description of the Dynamic Accuracy Test Set. This is followed by a
more detailed operating theory. The operation of each group is described briefly to the assembly
level only. Detailed component level circuit theory is not provided.

illustrates the components and interconnects of the Dynamic Accuracy Test Set.
The main function of this Test Set is to
provide a means to
measure
the
receiver's relative power
linearity of the network analyzer. The Test Set consists of four main
non-RF
components: a
controller module, a 39495EXT module, distribution board for programmable step attenuator, and
front panel LED indicator
circuits
